A kind of bluetooth earphone antenna and its design method and a kind of bluetooth earphone

Abstract

The invention discloses a Bluetooth earphone antenna and a design method thereof, and Bluetooth earphones. A line control box of the Bluetooth earphones is in the shape of a regular triangular prism, and a PCB comprising a Bluetooth chip is arranged at a position in the middle of a cavity of the line control box and is close to one side surface in parallel; the antenna comprises an antenna main body, an antenna feed portion and an antenna grounding portion which start from the same summit of the line control box not close to the side surface of the PCB in parallel; and the antenna main body wires along a side edge, and the antenna feed portion and the antenna grounding portion wire respectively along different bottom edges of the line control box and are correspondingly in electrical connection with a feed point and a grounding point in the PCB. The structure is stable, and antenna deformation caused by vibration or poor antenna performance caused by breaking can be avoided; the overall structure of the antenna enables structural space to be better utilized, the antenna is enabled to have better omnidirectional performance and broadband performance, the influences exerted on antenna resonance by surrounding environments in an earphone application process are reduced, and the design is applied to small-dimension Bluetooth earphones.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphones, in particular to a bluetooth earphone antenna, a design method thereof and a bluetooth earphone. Background technique [0002] Because of the portability of Bluetooth headsets, people are willing to use them on various occasions, especially when they are exercising, they can listen to music, answer calls, etc. through Bluetooth headsets, which brings great convenience to people during exercise. The requirements for the performance and appearance of Bluetooth headsets are getting higher and higher. In order to increase the competitiveness of products, manufacturers have launched Bluetooth headsets with small sizes and metal shells to improve their portability and appearance and attract more consumers. [0003] The reduction in size and the addition of metal casings will inevitably increase the difficulty of antenna design. If the existing antenna design is still used, such as monopole...
